Just as much evidence exists to indicate that the act of composing this article is reality as there is evidence to demonstrate the opposite.

In Meditation I , Descartes stated that if one were mad, even briefly, the insanity might have driven man into believing that what we thought was true could be merely our minds deceiving us.

    He also stated that there could be ' some malicious, powerful, cunning demon ' that had deceived us, preventing us from judging correctly. Descartes argued that all his senses were lying and since your senses can easily fool you, his idea of an infinitely powerful being must be true as that idea could have only been put there by an infinitely powerful being which would have no reason to be deceitful to him.

    Skepticism in the Modern World

    While methodic doubt has a nature, one need not hold that knowledge is impossible in order to apply the method of doubt. Indeed, Descartes' attempt to apply the method of doubt to the existence of himself spawned the proof of his famous saying, " Cogito, ergo sum " I think, therefore I am.

    That is, Descartes tried to doubt his own existence, but found that even his doubting showed that he existed, since he could not doubt if he did not exist. From Wikipedia, the free encyclopedia.
